Abstract
Изобретение относитс к измерительной технике, а именно к устройствам дл калибровки датчиков звукового давлени . Целью изобретени вл етс повышение точности и надежное ти0 Устройство содержит пистон- фон 1, выполненный в виде привода 3 вращени , на валу которого размещен эксцентрик 4„ В отверсти х обоймы размещены подпружиненные поршни 5, контактирующие с поверхностью эксцентрика 4 „ Пистонфон 1 размещен в корпусе 8 камеры, в котором выполнено гнездо 10 дл калибруемого датчика 11. Привод 3 вращени снабжен блоком 13 реверса и источником 12 питани . При включении привода 3 начинает вращатьс эксцентрик 4, заставл поршни 5 совершать обратнопоступа- тельные движени . В результате в камере 8 создаютс звуковые колебани известной частоты, действующие на калибруемый датчик 11. С помощью блока 13 переключают полюса привода 3 и измен ют направление его вращени , что повышает точность и надежность работы за счет уменьшени и равномерности износа концов поршней. 3 ил. СThe invention relates to a measurement technique, namely, devices for calibrating sound pressure sensors. The aim of the invention is to improve the accuracy and reliable ty0. The device includes a piston-1, made in the form of a rotation drive 3, on the shaft of which an eccentric 4 is placed. 8 of the chamber in which the socket 10 is made for the sensor to be calibrated 11. The rotational drive 3 is provided with a reverse unit 13 and a power source 12. When the actuator 3 is turned on, the eccentric 4 begins to rotate, causing the pistons 5 to perform backward movements. As a result, sound oscillations of a known frequency acting on the sensor being calibrated are created in chamber 8. By means of unit 13, the poles of actuator 3 are switched and their direction of rotation is changed, which improves the accuracy and reliability of operation by reducing and evenly wearing the ends of the pistons. 3 il.
